摘要
针对钼板轧制过程中,撕裂轧废现象严重等问题,对钼板轧制常用的典型轧辊辊形,如直线廓形轧辊、CVC轧辊辊形以及SMART Crown轧辊辊形,从辊形曲线设计、轧制应力、破坏情况进行比较,提出一种优化设计的辊形以避免或减少边裂现象。结果表明,优化设计的辊形轧辊施加给钼板轧制应力是现有生产轧辊的168%,而破坏值却是4种辊形轧辊中最小的。
Aiming at the serious defective material and tearing in rolling process of molybdenum plate,the common roll crown,such as line roll shape,CVC roll shape and SMART Crown were analyzed comparatively in curve design of the roll shape,rolling stress and damage.And an optimal roll shape was designed to solve the above problem.The results show that optimal roll＇s rolling stress is 1.68 times as much as that of present roll,however,damage value resulted from optimal roll shape is the least among the four rolls＇ shapes.
